SHOCK-ABSORBER.

Application led August 7, 1913.

To all wimmit may conform Be it known that l, OWEN T. Boco, a citizen otthe United States, and resident of lfloboken, county of Hudson, andState of New Jersey, have made a new andhusetul Invention inShock-Absorbers, of which the following is a specification.

My inventionis directed particularly to shock absorbers for wheeledvehicles, suoli as carriages, Wagons, automobiles, motor trucks, and thelike, and it has for its objects, First, to produce a shock absorber'which will be simple, cheap and etlicieut. Second, to produce a shockabsorberl which may be quickly attached to and detached from thevehicle. Third, to produce a shock absorber in which air` at atmosphericpressure is utilized in hermetically sealed cells located at ditferentheights and formed in any elastic medium.

For a full and clear understanding of the invention such as will enableothers skilled in the art to construct and use the same, relerence ishad to the accompanying drawings, in which,

Figure l is a sectional view of my 1mproved shock absorber and the meansfor attaching the same to the springs of a carriage. Fig. 2 is a planView of the same with the means for attaching it to the springs oi thecarriage removed; and Fig. is a front elevational view of the same upon`a smaller scale, showing it as applied to the spring of a carriage.

Referring; now to the drawings in detail, tl and 9 represent the springsot a vehicle secured together at their ends in the usual manner andsustaining my improved shock absorber at the center thereof inl which land 2 are a series of cup-shaped disks ot soft rubber or other highlyelastic material. In constructing these disks they are formedpreferablyin a. mold and at the same time a number of cells 3 are moldedtherein, which cells are open at their bottoms. These disks are thenvulcanized tothe desired degrec, preferably so as to make the elasticityas great as possi-ble or as near the same as that of atmospheric air,for a purpose to be hereinafter described. The disks are then coated onboth sides with a covering of any preferred cement which will tightlyand hermetically seal them together, being'careful to locate therespective disks one above the other and in such manner that all thecells ot Specicaton of Letters Patent.

one disk in each series, except the central one, are staggered withrelation to all ot the others, so as to forni the strongest possibleconstruction, as clearly shown in Fig. l. The entire structure is thensubjected to heat and pressure, il necessary, such as will effectua-llyunite the parts together and virtually make one integral mass, the topsof eachY disk or cup etfectually sealing the cells oi the cup above it.

with the elastic shock absorber firmly heldin position by the verticalcircular flanges, as shown. .i i

l do not limit myself to the specific inven tion disclosed in thedrawings and hereinbefore described, as I believe it is broadly new withme to provide a shock absorber which combines the elastic effect of airat atmospheric pressure, when hermetically' sealed in two or more seriesof cells of soft rubber or oth er yielding material. so that the jointelastic efl'ect of the several series oi cells, located at differentheights, and the rubber or other yielding' material will give the bestresults. l have discovered that such a shock absorber possesses thehighest possible elasticity and reduces the shocks oli'ered by a vehiclemuch more than is possible with soft rubber or other elastic materialalone, 'which l am aware has heretofore been used largely in the artsfor the purpose ot pre venting shocks or blows due to the Weight carriedby the springs ol vehicles.

l also desire it to be understood. that my invention is capable ot wideuse in the arts for the purpose named and l do not limit myself to anyspecic use or appliance.

I may make this shock absorber of raw rubber by locating cells ot'vulcanized rub ber throughout the mass thereof and 'then vulcanize thewhole.

lvl-living thus described my invention what l claim and desire to secureby `Letters Patent of the United States is` l. A shock absorberembracing atmoslll@ plierie air inelosed in a plurality of hermetirall)Ysealed Cells substantially the saine elastici@r as the air.

t3. shock absorber Composed of a pluof cells loeated in the lowerportions of said cells Filled with air at substantially atmos- 1 phericpressure, said cells being herinetically sealed and lorfat'erl attlitl'ereuti heights.

said Cells being staggered with relation to each other in the variousdisks.

S. A shock absorber embracing a plurality of cup-shaped rubber diskseach having cells in its lower surface and all held together by rementso as to constitute one. integral mass; together with means for securingthe saine to the springs of a vehicle.
